Description

Technical Field

[0001] This utility model relates to the technical field of air purification devices, specifically an air purifier. Background Technology

[0002] As people's living standards improve, air purifiers are increasingly being installed in homes to purify indoor air. Air purifiers generally have two types of airflow settings: front-in and side-in. Front-in purifiers allow air to enter from the front and diffuse out from the top after purification; side-in purifiers allow air to enter from one side and diffuse out from the other side or the top after purification. However, these airflow settings are ineffective against fine dust on or near the ground. Experimental tests have shown that suction alone cannot draw dust from the ground into the air purifier for filtration. The dust will slowly settle on the ground, and once the air purifier is turned off, the dust may re-enter the indoor air, reducing the air purification effect. Utility Model Content

[0003] To address the problem that existing air purifiers cannot effectively draw in and filter ground dust using suction, this invention provides an air purifier that includes top and bottom air outlets. This air outlet can blow up ground dust and near-ground dust so that it can be drawn into the central filter for filtration. It also prevents dust from settling on the ground, thus achieving a better air purification effect.

[0004] Therefore, the present invention provides the following technical solution: An air purifier includes a cylindrical body, an upper impeller assembly, a lower impeller assembly, and a middle filter module. The cylindrical body has a top chamber at the top, a bottom chamber at the bottom, and a middle chamber in the middle. The top chamber has a ventilation base plate at its bottom, and the bottom chamber has a ventilation top plate at its top. The cylindrical body has ventilation holes on its sides that mate with the top, bottom, and middle chambers. The upper impeller assembly, located in the top chamber, includes an upper impeller and a motor. The upper impeller is connected to a motor shaft and draws air in from the bottom, and exhausts air from the side or the top. The motor is fixed inside the top chamber. The lower impeller assembly, located in the bottom chamber, includes a lower impeller and a motor. The lower impeller is connected to a motor shaft and draws air in from the top and exhausts air from the side. The motor is fixed inside the bottom chamber. The middle filter module is located in the middle chamber. The top of the middle filter module is flush with the bottom of the ventilation base plate, and the bottom of the middle filter module is flush with the top of the ventilation top plate.

[0005] In this design, the air purifier uses a central air intake and filters the air, which then exits from both the top and bottom. This design blows up dust particles on the ground, making it easier to introduce them into the central filtration unit (filter module) for filtration. The filtered air is then introduced into the top or bottom chamber through the ventilation base plate and ventilation top plate, and then discharged by the upper or lower impeller. After the air purifier has been running for a period of time, the indoor air can be purified. The upper and lower impellers are each driven by a motor, which is connected to the shaft of the upper and lower impellers. The upper and lower impellers are connected to the ventilation base plate or ventilation top plate through two motors, respectively. The motors are connected to the control device of the air purifier, which is connected to an external power source.

[0006] As a preferred embodiment of this utility model, the cylindrical body includes a barrel-shaped upper hatch cover, a ventilation bottom plate, a barrel-shaped middle compartment, a ventilation top plate, and a barrel-shaped lower hatch cover connected in sequence. The components of this embodiment can be interconnected using male and female snap-fit ​​connections, facilitating assembly.

[0007] As a preferred embodiment of this utility model, the cylindrical intermediate chamber includes a vertical support frame and two interconnected semi-cylindrical bodies. The vertical support frame is located inside one of the semi-cylindrical bodies, and its two ends are connected to a ventilation bottom plate and a ventilation top plate, respectively. The two semi-cylindrical bodies are fitted together to form the cylindrical intermediate chamber, and each of the two semi-cylindrical bodies has an adsorption magnet on its contact surface. In this design, the intermediate chamber is stably supported by multiple pillars, ensuring the stability of the middle layer structure during device operation. The cylindrical intermediate chamber is designed as a structure of two semi-cylindrical bodies, each occupying half of the chamber, which can be opened in half. Magnets are cleverly placed at the point where the two semi-cylindrical bodies are in close contact. This design facilitates filter replacement and maintenance, and also ensures a tight closure of the intermediate chamber when closed through the adsorption of the magnets, preventing the leakage of unfiltered air and further guaranteeing the purification effect.

[0008] In a preferred embodiment of this utility model, the upper and lower impellers include a circular central plate with a rotating shaft hole at its center. Multiple evenly distributed arc-shaped fan plates are located on the top and bottom surfaces of the central plate near the circumference. One end of each arc-shaped fan plate is connected to the central plate, and the other ends are interconnected via rings. The upper and lower impellers exhaust air towards the sides of the arc-shaped fan plates. The central plate is connected to the motor shaft via the rotating shaft hole. This upper and lower impeller structure is suitable for side exhaust. During exhaust, air in the middle of the upper and lower impellers is expelled, creating a relative vacuum, allowing filtered clean air to be drawn in from the central filter module and continued to be exhausted. The motor shaft passes through the rotating shaft hole and connects to the central plate.

[0009] In a preferred embodiment of this utility model, the upper impeller is provided with a conical rotating plate, the top of which has a rotating shaft hole, and multiple arc-shaped fan blades are provided on the outer surface of the top of the conical rotating plate. These arc-shaped fan blades are interconnected at the top via an annular ring. The upper impeller exhausts air towards the top of the arc-shaped fan blades, and the top of the top chamber has an exhaust vent. This design employs a top-outlet structure: an air outlet is provided at the top of the device as a channel for purified air exhaust; the upper impeller continuously draws in filtered clean air from the central filter module and exhausts it outwards. This optimized design ensures that the purified air is evenly and stably delivered from the top, avoiding airflow turbulence, effectively covering the surrounding space, and improving indoor air circulation efficiency. The motor shaft passes through the rotating shaft hole and connects to the conical rotating plate.

[0010] In a preferred embodiment of this invention, the central filter module comprises multiple layers of filters. The central filter module is the core purification area of ​​the device, located between the upper and lower impellers. Multiple layers of filters, such as pre-filters, HEPA filters, and activated carbon filters, can be installed inside, and a multi-layered structure can be configured as needed.

[0011] Compared with the prior art, the present invention has the following advantages: it includes top and bottom air outlet devices, which can blow up the dust on and near the ground so that it can be sucked into the middle filter device for filtration, and can also prevent the dust from settling on the ground, thus achieving a better air purification effect; the filter element is easy to replace.
